IMPROVEMENT IN COOKING-STOVES.

The Schedule referred to in these Letters Patent and making part of the same.

lage of Neenah, in the county of \Vinnebago, and State of W'iscousm, have invented a new and improved Extension-Top for Cooking-Stoves; and I do.

hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specifica tion.

The nature of my invention consists in the extension of the top of a cooking-stove behind the smokepipe or escape-flue; the pan or hotair chamber and flue of such extension being so constructed and arranged, relatively to the main body of the stove, and provided with dampers, that the heat may be directed into the extension, either directly from the fire-place, 'or when. the same shall have been first directed, in the usual manner, downbeneath the oven, in both cases the smoke passing from the extension-flue to the ordinary escape-fine. The heat may likewise be cut oti from the extension, thus allowing, as, for instance, a water-tank, to cool, and the use of the stove in the ordinary manner. The top of the extension, as well as the body of the stove, are provided, in the ordinary manner, with a movable covering, that will admit of receiving pots, kettles, cooking-utensils, or a wash-boiler or watertank.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a perspective view of a fragment of a stove, with my extension attached, the top plate of the stove being removed.

Figure 2 is a plan of the top of a stove, with the extension, the covering or top plate of the stove being represented by dotted lines.

Figure 3 is a vertical cross-section, cutting through the dotted lines 'z z, fig. 2, showing the ordinary fines.

Figure 4 is a fragmentary vertical longitudinal section, cutting through the dotted line a: x, fig. 2.

Figure 5 is a horizontal section, cutting through the dotted lines If y, in figs. 3 and 4, showing the ordinary division of lines beneath the oven.

Figure 8 is a horizontal slide-damper seen at h, in figs. 1, 4, 6, and 7.

Figure 9 is a two-part rolling damper, seen at i 'i, in figsQl, 6, and 7.

Figure 10 is the ordinary damper used'forlcutting oil the direct escape of the heat and smoke, and diverting the same beneath the oven, and is seen at o, in figs. 1, 6,'and 7.

A is an ordinary stove with my extension-top attached, and seen at B.

c is the ordinary main flue and hot-airchambcr.

(Z is my extension-flue and hot-air chamber.

1: e, figs. 3, 6, and 7, are vertical descending fines, connecting with horizontal fines c c, fig. 5, and with return-flue f, and ascending-fines f and g, fig. 4.

I1. is a slide-damper, adjusted by the handle 71.

ii is a two-part rolling damper, adjusted by the handle 1.

o is a single-plate rolling damper, adjusted by the handle 0'.

k is the ordinary escape-flue or smokepipe.

The arrows seen in the several diagrams show. the currents of the hot air and smoke, according to adjustmcnt.

To use the stove in the ordinary manner, without the hot air entering to the extension, the damper.

0 is adjusted horizontally, the damper 5'2; is adjusted vertically, and the damper h is drawn out, all it;- seen in fig. 6, thus allowing the hot air and smoke to escape in the ordinary manner, directly from the main flue c to the escape or smoke-flue 7c, and al-- lowing the option of heating the main part of the stove alone.

To give direction to the hot air from the main flue c to the hot-air chamber (Z, in the extension, and thus cause both the main part and the extension to be heated, adjust the dampers '5 i, 0, and 71-, as shown imfig. 1, and the hot air will passinto the chamber (l, and from thence to the escape. or smoke flue h.

To give direction to the hot air from the main flue c, beneath the oven, and from thence to the extension, adjust, as seen in fig. 7, the single damper 0 vertically, the two-part damper '1 l vertically, and the slide-damper 71, to cut off the direct current from the return-flue f to the escape-flue h. Thus adjusted, the hot air and smoke will pass, as indicated by the arrows, from the main .flue 0 into the vertical fines c e, thence down and into-the horizontal fiuesc e, beneath the oven, thence in turn into the returnfiues f and f, thence through the line g, as seen in figs. 4 and 7, into the extended chamber (hand from thence into the escape or smoke-flue 7;.

Thus it is that the several adjustments of the dampers allow the option of directing the heat to the extension direct from the fire-chamber, or aft-er the current of hot air has first passed beneath and heated the oven, and then to the extension; or the currents of hot air may be cut off entirely from the extension. 4

It is apparent that my'ext-ension-top may also be applied to stoves containing a different combination g, dampers h and "L i, when arranged relatively to the stove A, provided with damper o, flues e e e e f and f, or other accessories of a similar or equivalent character, as and for the purposes set forth.
